This module provides a function
I18N::LangTags::List::name( langtag )
that takes
a language tag (see I18N::LangTags)
and returns the best attempt at an English name for it, or
undef if it can't make sense of the tag.
The function I18N::LangTags::List::name(...) is not exported.
This module also provides a function
I18N::LangTags::List::is_decent( langtag )
that returns true iff
the language tag is syntactically valid and is for general use (like
"fr" or "fr-ca", below). That is, it returns false for tags that are
syntactically invalid and for tags, like "aus", that are listed in
brackets below. This function is not exported.
The map of tags-to-names that it uses is accessible as %I18N::LangTags::List::Name, and it's the same as the list that follows in this documentation, which should be useful to you even if you don't use this module.
Internet language tags, as defined in RFC 3066, are a formalism for denoting human languages. The two-letter ISO 639-1 language codes are well known (as "en" for English), as are their forms when qualified by a country code ("en-US"). Less well-known are the arbitrary-length non-ISO codes (like "i-mingo"), and the recently (in 2001) introduced three-letter ISO-639-2 codes.
Remember these important facts:
Language tags are not locale IDs. A locale ID is written with a "_"
instead of a "-", (almost?) always matches m/^\w\w_\w\w\b/
, and
means something different than a language tag. A language tag
denotes a language. A locale ID denotes a language as used in
a particular place, in combination with non-linguistic
location-specific information such as what currency is used
there. Locales also often denote character set information,
as in "en_US.ISO8859-1".
Language tags are not for computer languages.
"Dialect" is not a useful term, since there is no objective criterion for establishing when two language-forms are dialects of eachother, or are separate languages.
Language tags are not case-sensitive. en-US, en-us, En-Us, etc., are all the same tag, and denote the same language.
Not every language tag really refers to a single language. Some language tags refer to conditions: i-default (system-message text in English plus maybe other languages), und (undetermined language). Others (notably lots of the three-letter codes) are bibliographic tags that classify whole groups of languages, as with cus "Cushitic (Other)" (i.e., a language that has been classed as Cushtic, but which has no more specific code) or the even less linguistically coherent sai for "South American Indian (Other)". Though useful in bibliography, SUCH TAGS ARE NOT FOR GENERAL USE. For further guidance, email me.
Language tags are not country codes. In fact, they are often
distinct codes, as with language tag ja for Japanese, and
ISO 3166 country code .jp
for Japan.
The first part of each item is the language tag, between {...}. It is followed by an English name for the language or language-group. Language tags that I judge to be not for general use, are bracketed.
This list is in alphabetical order by English name of the language.
